Applied Mathematician/Physicist (Analytic Modeling and Data Analysis)

The Johns Hopkins University Applied Physics Laboratory (APL), a national leader in scientific research and development, is located midway between Baltimore and Washington, DC. is seeking an Applied Mathematician/Physicist (Analytic Modeling and Data Analysis).

Job Summary: Develop mathematical models for inertial measurement units (IMU), Global Positioning System (GPS) receiver measurement data, and other sensor systems (e.g. RADAR). Develop/understand the mathematical algorithms necessary to evaluate guidance and navigation errors using state of the art estimation techniques, to include Kalman Filters and Maximum-Likelihood estimation. Analyze measurement data and understand/develop the corresponding mathematical models to assess designs of future missiles and reentry vehicles. Write weapon system evaluation reports, and participate in technical meetings with sponsors and external organizations.


  • Evaluate the accuracy and performance of missiles and reentry vehicles using mathematical models, simulations, telemetry data from onboard systems and instrumentation, and off board metric measurements; in particular, inertial navigation system and Global Positioning System (GPS) measurements.(20%)
  • Develop/understand the mathematical models describing measurement data from inertial measurement units, GPS receivers, RADARS, and potentially other measurement systems. Develop/understand the algorithms required to estimate guidance and navigation errors using Kalman Filters and other estimation techniques. (35%)
  • Write software (primarily Matlab) required to process data from IMUs, GPS receivers, RADARS, and potentially other measurement systems. (35%)
  • Participate in technical meetings and working groups that assess and monitor weapon system performance and that evaluate proposals for future missiles and reentry vehicles and their navigation systems.(5%)
  • Write weapon system evaluation reports and present analysis results at sponsor program reviews.(5%)

Note: This job summary and listing of duties is for the purpose of describing the position and its essential functions at time of hire and may change over time.

Required Qualifications:

  • Ph.D. in Applied Mathematics or Physics.
  • Relevant experience in one or more of the following areas: inertial navigation, GPS navigation, vehicle trajectory modeling/simulation, estimation theory (e.g. Kalman Filtering).
